Mmmm, That bearing sure shows classic overloading. Methinks it's time to step'em up to something tougher or find the cause (detonation?).

The fuel guys simply use Micro Babbit bearings and flatten 'em out instead of the fretting; then just change 'em every run. Saves the cranks though...!

True but they've got zippers on everything AND 20 guys.
